Prepare the Ground Beef: Heat a large skillet over medium heat. Add the ground beef and cook, breaking it into small crumbles as it browns. Stir occasionally to ensure even cooking and prevent sticking. The goal is to achieve a rich, golden-brown color for maximum flavor.
Add Seasoning and Aromatics: Once the beef is fully browned, add the Worcestershire sauce, brown sugar, onion & herb seasoning, and minced onions. Stir well to combine. Continue cooking for about 5 minutes until the onions become soft and translucent, and the mixture takes on a deep, savory aroma. This step builds the flavorful base for your baked beans.
Combine Everything: In a large baking dish, add the cooked beef mixture along with the baked beans. Stir in the chopped onions and green bell peppers, mixing until all ingredients are evenly distributed. The vegetables will add freshness and a slight crunch that balances the sweetness of the beans.
Bake the Beans: Preheat your oven to 375°F (190°C). Cover the baking dish with foil to help retain moisture and bake for 30 minutes, or until the beans are bubbling around the edges and the bell peppers have softened slightly. The heat will allow all the flavors to meld into a deliciously rich, thick sauce.
Rest and Serve: Remove the dish from the oven and let it rest for a few minutes before serving. Garnish with fresh herbs or a sprinkle of shredded cheese if desired. Serve warm as a hearty side dish or even as a main course.
